"1o Claims.

This invention relates to a stranding machine or an apparatus for putting twist into Vone or laying several strands of work and is directed more particularly to the double twist type of machine wherein two twists or lays are placed in the strand for each single revolution of the flyer.

Heretofore, in the use of a machine of the above type if one of the several strands breaks the broken end vmay pass into a tubular spindle before the machine could be stopped and the end pieced up, which, requires considerable Work in rethreading the machine to pass the broken end into the hollow spindle. Because ofthe mountings of the creel or packagecarrier which substantially floats upon rotating spindle with the rotating twist imparting member located below the creel difficulty is encountered in the applying of anystop motion to a device of this character.

One of the objects of this invention is to provide in a machine of this character a stop motion which will effectively control the operation of the apparatus so-that the apparatus may be stopped immediately should a break in one of the strands occur.

Anotherobject of this invention is to provide struction, as will be more fully *describedV andparticularly pointed out in the appended claims.

This inventionis directed more particularly to a stop motion which forms a part of a complete cable making machine which is the subjectmat- ZOter 'of my co-pending application Ser. No. 517,859

to which reference is made fora more complete showing of the operating parts of thecomplete machine. l

With reference to the drawings Ill designates a 25 spindle which is driven from some source of power such for instance as an lelectric motor II by means of a` belt extending about the pulley of the motor and about the pulley I2 fixedly secured upon the spindle I0. The spindle is suitably rokr:150 tatably mounted in a casing I3 01 "framework whichis a stationary part of the machine.`

A creel support I4 has a hub `I5 which is rotatably supported upon a spindle in spaced relation to the framework or casing I3 of the ma- A35 chine. A rotary yer member designated gen- `erally` I6 is ilxed to the spindle to `rotatetherewith and consistsof a hub portionfl'l with discs I8 and I9 secured thereto for rotation therewith. `Shafts 2U are rotatably mounted in sleeves 20 :45 upon eachrotation of the spindle. A belt 25 embraces pulley 22 and the hub 26 which is-fixed on creel support It so that as the shaft 20revolves the drive will tend to movethe` Creel I 4 inthe opposite direction. It vwill thus be apshafts 20 they will reverselydrive the creel I4 so las to maintain the creel in` the Asame relative position to the stationary framefthus the creel I4 will 'have no rotation relative to the" casing I3 The package support |4 has spindles 30 extending upwardly therefrom, there being shown six of such spindles in the illustration herein. Each of these spindles retains a package 3| mounted thereon by means of the wing nut 32. The strand of wire on such package 3| extends from the package about the guide post designated generally 33 as shown at 434 in Fig. `3, `thence 'over the guide sheave 35 and about the drums 36 and 31 a plurality number of times and then over the guide sheaves 38 and 39 and into the hollow spindle |0.

Certain of the guides designated generally "38 are utilized for supporting of the upper deck -40 upon which spindle 4| is mounted for the reception of a package 42 of strand material which is held in position 4by the wing nut 43. A guide post designated generally 44 (see Fig. 2) is mounted upon this upper deck 40 while strand material 45 may extend from the package 42 about this guide yfill and thence :to a sheave 46, about the drums 41 and 48 and thence over )another sheave 49 andl second :shift 50 to .extendfthrough :the hollow spindle l .and serve .as a core 'about lwhich the cable is to be formed.

'The cable designated .52| @emerges from the 4spindle over ;a :guide shear/.e152 and `thence extends about a guide sheave 53 which is .rotatably mounted near the periphery ofthe -disc I 8, thence this cable :extends upwardly over ,suitable guides to some packaging means, :such lfor .instance as is more fully yemalained `in my cofpending application above .referredtd The portion .of the cable 'extending upwardlytrom'the sheave 53 as it revolves follows substantially the surface of a cone which would completely embrace the creel :thusmaking it impossible tofextend ianywire or part to thecreel-latera'lly-ogf'the .spindle along the vertical extent of .the work-loop.

Each of the guide posts -33 .(seeFig. 9) aconsists of a solid upstanding anember :55 which ,is threaded .as at 56 in-to lthe creelsupport i|4. ,A bearing 51 is provided on this member,.5.5w-hich is held in 'position by a spring ring.5'8, a similar `bearing is provided .near .the 'upper end fof they member, and a sleeve 59 is rotatably supported on these bearingswhich may freely rotate as -the strand designated .34 fis'drawn about v.this guide post. A collar for circuit closing memberfl .is

slidably related tothe sleeve-59 and lwill move .by-

gravity to -the lower ,part .of .the .sleeve when free to do so. This lcollar has an outwardly rounded ange 6| to rest Aupon ythe strand .material 34 -so as to be supported ithereby and prevented from gravitatingto its lower position .so ylong as :the strand material extends about .the post. However, when thisstrand material breaks fthe collar Will slide to its lowermost position.

An annular electrical Vcontact strip :6 3 is sup- .ported by insulation -64 from the :creel i4 .and ,is provided with openingsf65 suilicient so as tospace the contact strip fromeach of the jguide posts which extend therethrough. An electrical connection may bemade between the strip --63 -and post by the collar 'when in its flowermost position.

The p-ost .44 is similar-:to lthepost 33 but is mounted on the upperdeck 140 byl thegportion .56 thereof to bethreaded into the :deck-"40 through an insulation'rbushing .65 (seeFig. 8) which-is shouldered as lat 66 to support the arm 161 which extends therefrom .in spaced relation .to thedeck This arm .61:-is thus insulatinglyfsupported lwith reference to the post whichhas `connectionwwith the structural Work of .thermachine ,A-similar sleeve or collar is carried by this post 44 and may bridge the conducting arm 61 and the post for establishing an electrical connection between them. The arm 61 is electrically connected to the annular member 63 by a rod 68 extending through the opening 69 in the deck 40 to insulate it therefrom and extending into a sleeve 10 which is electricallyr connected to the annular contact member 63.

The ange 12 of the creel is equipped with a boss 13 having a bore 14 (see Fig. 5) in which the insulating sleeve 15 is mounted. This sleeve car- -ries a brush 16 pressed by the spring 11 which may be adjusted by the threaded rod 18 that the desired pressure may be obtained and which rod is held in position 'by threadingly engaging a part of the bushing. Electrical connection is established between the 4brush 16 and the annular contact .63 by a strip 19 secured as at 80 to the member 63 and by nut 8| to the threaded rod 18 to establish electrical Iconnect-ion between them.

The lbrush 'L6 engagesan ,annular contact member :83 which is insulated as at 84 from the .disk i8 but so located that Vas the disk revolves this annular memberwill be engaged by the brush 16 at all times. An annular .member .6,5 carried on the underside of the disk |9 (see Fig. 7) is :electrical-ly connected to .the l.annular member 83 -by Ia strap ,84 `secured to these members bybolts y86 and 81 4through insulating bushings 8-8 in both lof said disks suchas by meansof nuts '89.

The framework |3 -is .alsoequipped with :a boss 90 (seeFig. `6) having a vbore 0| with insulating bushings 92 therein Awhich holds a threadedmember YBB to `adjustably yengage the spring 04 which urges the vbrush 39,5 aga-inst the annular contact member 85. A certain terminal arrangement Iby nuts 196 `and -91 enable the l:circuit lead V9.8 `to be .secured thereto.

The .electrical circuit-which .is involved in this mechanism consists -of ,power supplied through lines .|00 :and |0| rto Athe electrical lmotor |-l and through the control 02 providing Vterminals to be closed-by the switch |03. This switch isnor- .mally lclosed Abut may be Yopened by means of a solenoid |04 in a circuit :consisting of van {energizingsource |05 withterrninals ,|-06.and |01, one of which representstheannular contact 63 While the other represents Ithe ground of the machine, both of which maybe bridged by .the collardesignated generally '60 which spans these Itwo points in completing the circuit. in [the machine.

From the source of energy |05 the live contact 63 or ,61 as represented at |06 is energized through the insulated connections traced `by 98, `93, '94, 95, 85,86, 83, 16, 11, 18, 19,63 and'1`0, 68 to 6 1. The

' ground or return 'circuit is `throughthe frame of 'the machine.
